  • Overfill protection for suction drainage system
    Patent number: 5669892
    Abstract: The present invention is directed to a shut-off valve for a suction drainage system wherein flow of waste to a disposable container is stopped at a pre-determined volume which is less than the maximum capacity. A tubular sleeve is coaxially located around the shut-off valve. The shut-off below the maximum volume allows a safety margin for the waste container to be capped off without spilling or geysering.

  • Gelling treatment for suction drainage system
    Patent number: 5549585
    Abstract: A gelling system for treating waste, such as bodily fluids, comprises a sealed receptacle (20) including a lid (21) and a chamber (23) within the receptacle for receiving the waste, a waste inlet port (24) in the lid connected to the interior of the chamber (23), an outlet port (25) in the lid (21) for connection to a suction source; and a container (1) for storing waste-treating material (e.g. a gelling agent), and for dispensing the waste-treating material into the chamber (23). When the suction system is in use is the container (1) is unattached to the receptacle (20) but, when it is desired to treat waste within the chamber (23), the container (1) is freely attachable to the receptacle (20) by means of an elongate dispensing nozzle (8) on the container which connects with the waste inlet port (24) to dispense the waste-treating material into the chamber.

  • Waste agent reservoir for suction drainage system
    Patent number: 5543042
    Abstract: The present invention is directed to a waste treating reservoir for treating waste collected using an associated suction system. A disposable receptacle connected to an associated suction system includes a sealed chamber such as a liner and a lid with a pour spout. The waste treating reservoir includes a closed container with an open mouth for storing a waste treating agent. A cylindrical wall forms a diffuser cap and has an open end portion and a substantially closed end portion. The closed end portion has a plurality of apertures opening radially through the cylindrical wall. The open end portion of the cylindrical diffuser cap fits telescopically over the open mouth of the agent container. The reservoir system further includes a double-walled sleeve having an inner wall and a generally concentric outer wall for attaching the combined diffuser cap and agent container to the spout of the disposable receptacle lid.
